No. 13/686,105, filed on Nov. 27, 2012, which is a continuation application of International Application No. PCT/CN2012/075934, filed on May 23, 2012, which claims priority to Chinese Patent Application No. 201110448641.X, filed on Dec. 28, 2011, all of which are hereby incorporated by reference in their entireties.
The present invention relates to the field of wireless communications, and in particular, to a method and a base station for managing capacity of a wireless communication network.
With the rapid development of communication users and communication services, the existing cell resources cannot satisfy the increasing demand of traffic. Therefore, the capacity of a communication system needs to be expanded. Capacity expansion of the communication system may be implemented in the following manner the number of antennas is increased, and new cell resources are configured for antennas, so that new cell resources are added, and cell splitting is implemented. In this manner, the capacity of the communication system is improved, and cell resources are increased.
However, when the traffic is low, the existing network capacity needs to be managed to reduce system physical resources. In a multiple-antenna network structure, a method for reducing the system physical resources is cell combination, and specifically is, deleting cell resources of multiple antennas corresponding to multiple cells, or, deleting cell resources of multiple antennas corresponding to a same cell, and configuring, for the multiple antennas, cell resources which are the same as cell resources of another cell. In the foregoing implementation manner for cell combination, relevant devices, such as the antennas, are not turned off when the traffic is low, thereby wasting energy.

The base station manages multiple overlay networks covering a same coverage area. The multiple overlay networks covering a same coverage area include a type 1 overlay network with a sector combining function, and multiple groups of antennas corresponding to each type 1 overlay network are configured. One power amplifier is configured for each antenna, and the method includes: checking total traffic of all the overlay networks managed by the base station; if the checked total traffic is lesser than (i.e., less than) a preset load threshold, searching for the type 1 overlay network among all the overlay networks belonging to the base station; if there is only one overlay network belonging to the type 1 overlay network, determining the overlay network as a first overlay network; if there are multiple overlay networks belonging to the type 1 overlay network, determining the first overlay network according to network status parameters of the multiple overlay networks belonging to the type 1 overlay network, where the first overlay network is a type 1 overlay network which is managed by the base station and requires network capacity management; maintaining normal work of a power amplifier of at least one antenna in each group of antennas in the first overlay network, and turning off power amplifiers of one or more other antennas; and connecting the one or more other antennas to the power amplifier maintaining normal work in the groups in which the one or more other antennas are located so that sub-sectors corresponding to each group of antennas among the multiple groups of antennas are respectively combined into multiple large sectors.

Embodiment 1 of the present invention provides a method for managing capacity of a wireless communication network, which is applied to a base station. The base station provides one or more network with a multi-sector structure. The base station manages multiple overlay networks covering a same coverage area. The multiple overlay networks covering a same coverage area include a type 1 overlay network with a sector combining function. Each type 1 overlay network has multiple groups of antennas. One power amplifier is configured for each antenna. As shown in
101: Check total traffic of all the overlay networks belonging to the base station.

106: Connect the one or more other antennas to the power amplifier maintaining normal work in the groups in which the one or more other antennas are located so that the sub-sectors corresponding to the multiple groups of antennas are respectively combined into multiple large sectors.
In this embodiment, the foregoing steps may be executed by the base station or a system which manages the base station, which is not limited by the embodiment of the present invention.
In the method and the base station for managing capacity of a wireless communication network provided by the embodiment of the present invention, when the checked total traffic of the network is lower than the first load threshold, one overlay network requiring network capacity management is determined, the power amplifiers corresponding to some of the configured antennas are turned off, and the antennas are connected to power amplifiers corresponding to one or more other antennas which work normally. Therefore, the energy is saved at a prerequisite of ensuring normal work of the antennas.
Based on Embodiment 1, the embodiment of the present invention is described in detail with an example of a base station with overlay networks each of a 6-sector structure. An implementation manner based on other sector structures may be implemented based on the embodiment of the present invention and in combination with specific features of the other sector structures. The specific implementation manners are all technologies well known by a person skilled in the art, and therefore the implementation manners are not described in detail in the embodiment of the present invention.
Multiple overlay networks covering a same area are disposed on the base station with the overlay networks each of a 6-sector structure. The multiple overlay network includes a type 1 overlay network. As shown in
It should be noted that, in this embodiment, the power amplifier is provided by a remote radio frequency unit. The power amplifier of each antenna may be configured in the following manners.
Configuration manner 1: as shown in
Configuration manner 2: as shown in
It should be noted that the power amplifier may also be provided by a non-remote radio frequency apparatus, which is not limited by the embodiment of the present invention.
As shown in
201: The base station checks total traffic of all the overlay networks belonging to the base station in real time.
The total traffic of all the overlay networks belonging to the base station may be obtained in the following manner base station downlink Guaranteed Bite Power (GBP) is generated according to a base station downlink load factor, and then the traffic of the overlay network is obtained by performing processing according to the base station data downlink GBP. How to obtain the traffic is a technology well known by a person skilled in the art, which is not described in detail in the embodiment of the present invention.
202: If the checked total traffic keeps being lesser than a first preset load threshold, the base station searches for a first overlay network, where the first overlay network belong a type 1 overlay network requiring network capacity management in the base station.
That the total traffic keeps being lesser than the first preset load threshold may be as follows: the total traffic is keeping being lesser than the first preset load threshold in a preset time period, where the preset time period may be set by a user according to an actual situation, which is not described again in the embodiment of the present invention.
It should be noted that the base station searching for and determining the first overlay network may be implemented in the following manner, which specifically is: the base station searches for the type 1 overlay network among all the overlay networks belonging to the base station; if there is only one overlay network belonging to the type 1 overlay network, the base station determines the overlay network as the first overlay network; and if there are multiple overlay networks belonging to the type 1 overlay network, the base station determines the first overlay network according to traffic, working frequency point information or a continuous coverage situation of the multiple overlay networks belonging to the type 1 overlay network.
It should be noted that the working frequency point information includes a working frequency of the antennas configured for the overlay network, and that the continuous coverage situation of the overlay network indicates whether the cells covered by the sectors corresponding to the antennas configured for the overlay network are spatially continuous, which is not described again in the embodiment of the present invention.
It should be noted that one specific implementation of determining, by the base station, the first overlay network according to the traffic, working frequency point information or continuous coverage situation of the multiple overlay networks belonging to the type 1 overlay network may include the base station selecting an overlay network among the type 1 overlay networks as the first overlay network, where the overlay network has lowest traffic or a largest difference between its working frequency point and working frequency points of other overlay networks, or cells of the overlay network that are covered by the sectors corresponding to the configured antennas are spatially discontinuous.
203: The base station searches for a second overlay network, where the second overlay network may be an overlay network with lowest traffic among the overlay networks capable of covering a area covered by the first overlay network.
The second overlay network may be an overlay network of a 6-sector structure or an overlay network of a 3-sector structure. It is only required herein that the second overlay network is capable of covering the area covered by the first overlay network, which is not to be described again in the embodiment of the present invention.
The first preset load threshold may be determined by the user in the base station according to an actual situation, which is not limited by the embodiment of the present invention.
204: If the second overlay network is capable of bearing the traffic of the first overlay network, the base station performs migration of all the traffic of the first overlay network to the second overlay network.
It should be noted that, if the second overlay network is not capable of bearing the traffic of the first overlay network, the current network architecture remains unchanged, which is not described again in the embodiment of the present invention.
By executing step 204, it can be ensured that a user terminal, which accesses the first overlay network when the following steps are executed, obtains a desired service through the second overlay network, thereby guaranteeing service experience of the user.
205: The base station maintains working status of the power amplifiers, Af1, Af3 and Af5 on the first overlay network and turns off the power amplifiers, Af2, Af4 and Af6 on the first overlay network.
The first overlay network is converted from a 6-sector structure into a 3-sector structure by executing step 205.
If step 204 is based on the foregoing configuration manner 1, step 204 may include: the base station maintaining working status of the power amplifiers, Af1, Af3 and Af5 on the first overlay network and turning off the power amplifiers, Af2, Af4 and Af6 on the first overlay network.
If step 204 is based on the foregoing configuration manner 2, step 204 may include: the base station maintaining working status of the power amplifiers of Af1, Af3 and Af5 on the first overlay network, turning off the power amplifiers of Af2, Af4 and Af6 on the first overlay network, and turning off the remote radio frequency units of Af2, Af4 and Af6. On the basis of the configuration manner 2, after the first overlay network is converted from 6 sectors into 3 sectors, the remote radio frequency units are turned off. Therefore, the power consumption of the remote radio frequency units that do not need to work is reduced, and energy-saving of the system is better achieved.
It should be noted that, when the first overlay network is converted from the 6-sector structure into the 3-sector structure, which power amplifier of an antenna in each group of antennas is selected and turned off may be preset in the base station. A specific manner for the presetting is a technology well known by a person skilled in the art, which is not described in detail in the embodiment of the present invention.
It should be noted that, if more than one antenna is configured in a 60° sector, the power amplifiers of multiple antennas in each group of antennas may maintain normal work, and the specific implementation method is similar to the method provided in the embodiment of the present invention, and therefore is not described in detail in the embodiment of the present invention.
206: The base station connects Af2 to the power amplifier of Af1, connects Af4 to the power amplifier of Af3, and connects Af6 to the power amplifier of Af5 by turning on the converters so that every two 60° sectors corresponding to each group of antennas on the first overlay network are combined into one 120° sector, thereby forming three 120° sectors.
In step 206, because the antenna of which the power amplifier is turned off is connected to the power amplifier of the antennas in a same group by turning on a corresponding converter, it is ensured that, after two 60° sectors corresponding to each group of antennas on the first overlay network are combined into one 120° sector, two cell coverage areas of two 60° sectors corresponding to each group of antennas are the same as the cell coverage area of one 120° sector.
207: Delete some cells and network resources corresponding to the cells according to the traffic, the working frequency point information or the continuous coverage situation of the cells covered by the sub-sectors corresponding to the six antennas in the first overlay network.
A specific implementation manner of step 207 is that: a cell with lowest traffic and network resources corresponding to the cell are selected and deleted; or, a cell with a largest difference between its working frequency point and working frequency points of other overlay networks and the network resources corresponding to the cell are selected; or, the cell which is spatially discontinuous with other cells and the network resources corresponding to the cell are selected and deleted.
208: The base station performs migration of part or all of the traffic of the second overlay network to the first overlay network, where the part of the traffic is more than (i.e., greater than) or equal to a second preset load threshold.
That the base station performs migration of part or all of the traffic on the second overlay network to the first overlay network may be implemented in a load balancing manner. Implementing traffic migration by performing load balancing is a technology publicly known by a person skilled in the art, which is not described again in the embodiment of the present invention.
In addition, it should be noted that, after the network capacity of the first overlay network is reduced by executing step 201 to step 208, work of the first overlay network may be stopped, and migration of the traffic of the first overlay network may be performed if the traffic of the first overlay network is very low.
Further, after the execution of step 201 to step 208, the network capacity of the first overlay network is reduced. If the total traffic of the base station keeps being higher than a third preset load threshold, the capacity of the base station needs to be increased. As shown in
301: The base station checks the total traffic of all the overlay networks belonging to the base station in real time.
The specific implementation manner of step 301 is the same as that of step 201, which is not described herein again.
302: If the checked total traffic keeps being more than the third preset load threshold, the base station searches for and determines a first overlay network, where the first overlay network belongs to a type 1 overlay network requiring network capacity management in the base station.
It should be noted that, the searching for and determining the first overlay network may be implemented in the following manner, which specifically is: the base station searches for the type 1 overlay network among all the overlay networks belonging to the base station; if there is only one overlay network belonging to the type 1 overlay network, the base station determines the overlay network as the first overlay network; and if there are multiple overlay networks belonging to the type 1 overlay network, the base station determines the first overlay network according to the traffic, the working frequency point information or the continuous coverage situation of the multiple overlay networks belonging to the type 1 overlay network.
It should be noted that, specific implementation of determining, by the base station, the first overlay network according to the traffic, the working frequency point information or the continuous coverage situation of multiple overlay networks belonging to the type 1 overlay network may include the base station selecting an overlay network among the type 1 overlay networks as the first overlay network, where the overlay network has high traffic or a smallest difference between its working frequency point and working frequency points of other overlay networks, or cells of the overlay network that are covered by the sectors corresponding to the configured antennas are spatially continuous.
303: The base station searches for a second overlay network, where the second overlay network is an overlay network with the lowest traffic among the overlay networks covering a same coverage area as the first overlay network.
304: If the second overlay network is capable of bearing the traffic of the first overlay network, the base station performs migration of all the traffic of the first overlay network to the second overlay network.
By executing step 304, it can be ensured that a user terminal, which accesses the first overlay network when the following steps are executed, obtains a desired service through the second overlay network, thereby guaranteeing service experience of the user.
305: The base station turns on the power amplifiers corresponding to Af2, Af4 and Af6 on the first overlay network.
The first overlay network is converted from the 3-sector structure into the 6-sector structure through step 305.
When step 305 is based on the foregoing configuration manner 1, step 305 may be that the base station turns on the power amplifiers corresponding to Af2, Af4 and Af6 on the first overlay network.
When step 305 is based on the foregoing configuration manner 2, step 305 may be that the base station turns on the remote radio frequency units corresponding to Af2, Af4 and Af6 on the first overlay network.
306: The base station connects Af2 to the power amplifier of Af2, connects Af4 to the power amplifier of Af4, and connects Af6 to the power amplifier of Af6 by turning off the converters so that three 120° sectors on the first overlay network are split into six 60° sectors of which every two 60° sectors correspond to each group of antennas.
It should be noted that, when three 120° sectors on the first overlay network are respectively split into two 60° sectors, two cell coverage areas of two 60° sectors corresponding to each group of antennas are the same as the cell coverage area of one 120° sector.
307: Establish new cell and network resources corresponding to the new cell according to the traffic, the working frequency point information or the continuous coverage situation of the cells covered by the sub-sectors corresponding to the six antennas in the first overlay network.
A specific implementation manner of step 307 is that the new cell and the network resources corresponding to the new cell are selected and established in a working frequency point of six antennas of the first overlay network, or the new cell and the network resources corresponding to the new cell are established in a blank area of the cells covered by the sub-sectors corresponding to the antennas.
308: The base station performs migration of part of the traffic of the second overlay network to the first overlay network, where the part of the traffic is more than or equal to a fourth preset load threshold.
In the method for managing capacity of a wireless communication network provided in the embodiment of the present invention, a converter is controlled to implement that, when the sectors are combined, the base station may turn off the power amplifiers of some antennas in the condition of not affecting the quality of service, thereby saving the energy; moreover, only one converter apparatus is added, and the implementation is simple; furthermore, because the cell numbers of the cells covered by the sub-sectors corresponding to each group of antennas are the same, the network resources do not need to be reallocated when the sectors are combined, thereby reducing complexity of a wireless configuration resource algorithm, and solving the problems in the conventional art that the energy is wasted, implementation of the apparatus is difficult, and the wireless configuration resource algorithm is complex.
Further, when the traffic of the first overlay network keeps being higher than the preset load threshold, the base station may increase capacity by turning off a converter, thereby ensuring the quality of service.
An embodiment of the present invention provides a base station for managing capacity of a wireless communication network. The base station manages multiple overlay networks covering a same cell coverage area. The multiple overlay networks covering a same coverage area include a type 1 overlay network with a sector combining function. Multiple groups of antennas corresponding to each type 1 overlay network are configured. One power amplifier is configured for each antenna. As shown in

The determination unit 43 is configured to, when the search unit 42 finds only one overlay network belonging to the type 1 overlay network, determine the overlay network as a first overlay network; and when the search unit 42 finds multiple overlay networks belonging to the type 1 overlay network, determine the first overlay network according to network status parameters of the multiple overlay networks belonging to the type 1 overlay network, where the first overlay network is the type 1 overlay network which is managed by the base station and requires network capacity management.
The adjustment unit 44 is configured to maintain normal work of a power amplifier of at least one antenna in each group of antennas in the first overlay network determined by the determination unit 43 and turn off the power amplifiers of one or more other antennas. The adjustment unit 44 is also configured to connect the one or more other antennas to the power amplifiers maintaining normal work in the groups in which the one or more other antennas are located so that sub-sectors corresponding to each group of antennas among the multiple groups of antennas are respectively combined into multiple large sectors.
Optionally, the search unit 42 may further be configured to search for the type 1 overlay network among all the overlay networks belonging to the base station when the total traffic checked by the check unit 41 is lesser than the first preset load threshold.

Optionally, the determination unit 43 may be specifically configured to, when the search unit 42 finds multiple overlay networks belonging to the type 1 overlay network, determine the first overlay network according to traffic, working frequency point information or a continuous coverage situation of the multiple overlay networks belonging to the type 1 overlay network.
More specifically, in an embodiment, when the search unit finds multiple overlay networks belonging to the type 1 overlay network, the determination unit 43 may specifically select an overlay network among the type 1 overlay networks as the first overlay network, where the overlay network has lowest traffic or a largest difference between its working frequency point and working frequency points of other overlay networks, or cells of the overlay network that are covered by the sectors corresponding to the configured antennas are spatially discontinuous.
Optionally, as shown in
The migration unit 45 is configured to search for a second overlay network after the determination unit 43 determines the first overlay network, where the second overlay network is the overlay network with lowest traffic among overlay networks covering a same coverage area as the first overlay network, and performs migration of all the traffic of the first overlay network to the second overlay network if the second overlay network is capable of bearing the traffic of the first overlay network.
Further, as shown in
The network resource control unit is configured to delete some of the cells and the network resources corresponding to the cells according to the traffic, working frequency point information or continuous coverage situation of the cells covered by the sub-sectors corresponding to the antennas in the first overlay network after the adjustment unit 44 connects the one or more other antennas to the first power amplifiers in the groups in which the one or more other antennas are located, so that the combined sectors are capable of bearing the traffic of the remaining cells after the deletion.
Optionally, the network resource control unit 46 is configured to establish a new cell and network resources corresponding to the new cell according to the traffic, the working frequency point information or the continuous coverage situation of the cells covered by the sub-sectors corresponding to the antennas of the first overlay network after the adjustment unit 44 connects the multiple groups of antennas to the power amplifiers corresponding to the multiple groups of antennas.
In the method and the base station for managing capacity of a wireless communication network provided in the embodiment of the present invention, a converter is controlled to implement that, when the sectors are combined, the base station may turn off the power amplifiers of some antennas in the condition of not affecting the quality of service, thereby saving the energy, and solving the problem in the conventional art that the energy is wasted.
